Salam in your calculations you show that it is not isolated and then if you use a transformer then it is isolated in this case what kind of transformers would you use. a flyback transformer? i think a small one from a USB charger can fit? what do you suggest

[@jhunmorales2987]

Good day Sir. Amazing Video. I dont understand malay language but i still understood your video even without subtitle, you are that good. Sir, am just confused as i could not understand the audio, how is it that we still get 315v DC after connecting the 2 resistors in series with the output probes. Please can you explain? I am really interested in building this tester. Can it also test the values of Zener Diaodes? Thank you.

[@greenyelectronics]

resistors limits the flow of current only, not voltage. yes it can measure zener voltage

[@ScrewBot]

@@greenyelectronics Thank you so much.. But dont the resistors also work as voltage dividers in circuit? Limiting voltage?

Hello,,I also watched the video and made it with a 10w bulb converter,,And the resistance is 5w41k,,And the voltage is about red 2.1v, but it's thrilling when the probe is touched by both hands,,Is that so,,, the tester voltage is not connected by an electric shock. I'm curious, so I'm asking.
I'd appreciate it if you could answer me.
